Yusei Fudo is the only person to have performed this Summon. He first learned about the existence of a type of Synchro Summon stronger than Accel Synchro when he saw Bruno use three Synchro Monsters to perform a Delta Accel Synchro Summon (instead of the usual two for an Accel Synchro Summon).[1] Later, in his Duel against Z-one, Yusei discovered how to exceed even Bruno's limits, and used a total of five Synchro Monsters (one Tuner and four non-Tuners) to Limit Over Accel Synchro Summon "Shooting Quasar Dragon".[2]
